SETTING UP:
When one transmitter is used
1. First, insert the batteries into the Thermo-hygro transmitter. (see “How to
install and replace batteries in the Thermo-hygro transmitter“).
2. Immediately after and within 2 minutes, insert the batteries into Weather
station (see “How to install and replace batteries in the Weather
station”). Once the batteries are in place, all segments of the LCD will light
up briefly. Following the time as 0:00 and the "weather man" icon will be
displayed. If these are not displayed after 60 seconds, remove the
batteries and wait for at least 10 seconds before reinserting them.

49
3. After inserting the batteries into the transmitter, the Weather station will
start receiving data from the transmitter. The outdoor temperature/
humidity and the signal reception icon should then be displayed on the
Weather station. If this does not happen after 3 minutes, the batteries will
need to be removed from both units and reset from step 1.
4. In order to ensure sufficient 868 MHz transmission however, this should
under good conditions be a distance no more than 100 meters between
the final position of the Temperature Station and the transmitter (see notes
on “Positioning” and “868 MHz Reception”).

50
When more than one transmitter is used
1. User shall remove all the batteries from the temperature station and
transmitters and wait 60 seconds if setting has been done with one
transmitter before.
2. Insert the batteries to the first transmitter.
3. Within 30 seconds of powering up the first transmitter, insert the batteries to
the Weather Station. Once the batteries are in place, all segments of the
LCD will light up briefly. Following time as 0:00 and the "weather man" icon
will be displayed. If they are not shown in LCD after 60 seconds, remove the
batteries and wait for at least 60 seconds before reinserting them.

51
4. The outdoor temperature and humidity from the first transmitter (channel 1)
should then be displayed on the Temperature station. Also, the signal
reception icon will be displayed. If this does not happen after 2 minutes, the
batteries will need to be removed from both units and reset from step 1.
5. Insert the batteries to the second transmitter immediate after (in 10
seconds after) inserting battery to the weather station.
6. The outdoor temperature and humidity from the second transmitter and the
"channel 2" icon should then be displayed on the Temperature station. If this
does not happen after 2 minute, the batteries will need to be removed from
all the units and reset from step 1.

52
7. Insert the batteries to the third transmitter immediate after (in 10 seconds
after) inserting battery to the second transmitter.
8. Then within 2 minutes, the channel 3 outdoor data from the third transmitter
will be displayed and the channel icon will shift back to "1" once the third
transmitter is successfully received. If this is not happen, user shall restart
the setting up from step 1.
Note:
After the three transmitters have been set up, user may need to check the
readings displayed on the weather station against those being shown on the

53
transmitter displays, in order to ecognise on which channel each transmitter is
being presented.
IMPORTANT:
Transmission problems will arise if the setting for additional sensors is not followed
as described above. Should transmission problems occur, it is necessary to
remove the batteries from all units and start again the set-up from step 1.
9. Once the remote data has been received and displayed on the Weather
station, the DCF-77 time code reception is automatically started. This takes

54
typically between 3-5 minutes in good conditions.
Note:
•If after 10 minutes, the DCF time has not been received, press the SET
key to manually enter a time initially.
•Daily DCF reception is done at 02:00 and 03:00. If the reception at 03:00 is
not successful, then at 04:00 and 05:00 and 06:00 there are other tries,
until one is successful. If the reception at 06:00 is still not successful, then
the next try takes place at 02:00 next day.
•When this is successful, the received time will override the manually set

55
time. The date is also updated with the received time. (Please refer also to
notes on “DCF-77 Radio controlled Time” and “Manual Time Setting”).

HOW TO INSTALL AND REPLACE BATTERIES IN THE THERMO-
HYGRO TRANSMITTER
The Thermo-hygro Transmitter uses 1 x 3.0V, CR2032, Lithium
battery. To install and replace the batteries, please follow the steps
below:
1. Pull out the battery holder at the bottom of the transmitter.
2. Insert the batteries, observing the correct polarity (see

Note:
In the event of changing batteries in any of the units, all units need to be reset by
following the setting up procedures. This is because a random security code is
assigned by the transmitter at start-up and this code must be received and stored
by the Weather station in the first 3 minutes of power being supplied to it
BATTERY CHANGE:
It is recommended to replace the batteries in all units regularly to ensure optimum
accuracy of these units. (Battery life –see Specifications)
